hahahaha can't choose because all Op and Ed anime sounds good to me . SAO  LiSA Crossing field will be my first fav OP

I don't remember the if it's ending or Opening but Ignite-Aoi Eir(Sword Art Online) and i like all SAO opening and ending.

Wouldn't be myself if I said that best opening (for me, of course ) is not Konya wa hurricane from BGC 2033

Spoiler:

ending from SAO-2 = shirushi - LiSA
ending from k-on! = don't say lazy

For the opening, I say Higurashi no Naku Koro ni's first opening is my all time favorite, whereas the best ending goes to Psycho-Pass's season 2 ending Fallen (Egoist).

Hmm this is quite hard.

Opening = Air Gear (Chain by Back-on)

Ending = Death Note (Zetsubou Billy by Maximum the hormone)

OPENING: Tokyo Ghoul
ENDING: can't decide there are so many awesome ones ! [ FMA ending (with Shukan Sentimental), Durarara first ending, Magi second season  second ending and more .... ]

Shunkan sentimental is the best

Weird, no one said "Flyers - BRADIO", from Death Parade.


By far, one of the best.

For ED, i'm not used to listen the EDs... but I really liked the Shingeki no Kyojin Ending.

For ending, it's Shunkan Sentimental. It was my gateway to Scandal, and I loved it upon 1st hearing.
Opening...Always liked L'Arc en Ciel's Ready, Steady, Go

OP= SAO (Crossing Field by LiSA)
ED= K-ON! (Don't say lazy), Psycho-Pass (All Alone With You by EGOIST)

Harukaze, still my favorite song ever... Also Fairy Tail's first opening Snow Fairy by Funkist. And all of FMA Brotherhood's openings, they are awesome to be honest.
About the ending... I really like Magi's The Bravery by supercell nowadays. It is quite catchy if you don't hear the screams.   And Kalafina's Magia from Madoka Magica.
Oh, okay. This will be so long if I continue!  .tsk.

There are way too many that I like. My favorite opening is the first OP of Great Teacher Onizuka with the song Drivers High by L'Arc-en-Ciel. The second SAO opening with Innocence by Aoi Eir and the first One Piece opening are also ones I enjoyed a lot.

I also like openings with no vocals, Gungrave and Trigun are probably my favorites in that category.

My favorite ending is the Full Metal Alchemist one with Shunkan Sentimental.

who knows FAIRY TAIL? ^_^ sharing my english cover of FT's 7th OP, Evidence.

Opening two for Akatsuki No Yona: Akatsuki No Hana
Ending Four Fairy Tail: Kimi Ga Iru Kara

Opening Another: ALI PROJECT - Kyoumu Densen
Ending Beck: Dying Breed - My World Down

Opening: Miraikei Answer (Ore Monogatari)
Ending: Don't Say Lazy (K-On)

Everything from Bleach

My favourite opening remains Closer, by Inoue Joe (Naruto):

For the ending, I got 2 favs:

- Hello hello hello, by Good morning America (Dragon Ball Super)

- Galaxy, by キュウソネコカミ (Dragon ball Kai)
   https://www.youtube.com/watch?v=a_ldqS-Jh8w

Mine are: Yui - Again and Unravel from Tokyo Ghould. But I think that Tokyo Ghoul's Unravel is the ebst opening in Anime history :D

Shirushi (Sword Art Online II) by LiSA

Anything by Tsuneo Imahori such as:

"H.T." from Trigun
"Throwing Dice" from Hajime no Ippo (the riffs sound like Led Zeppelin's Moby Dick though)

Revised: Opening 1 of SAO, Crossing Field
Ending: Ending 2 of Aldnoah Zero, aLiez by Hiroyuki Sawano

Opening of Eden of the East (Oasis - Falling Down)

I don't usually pay attention to ending themes cuz that's when I go " well, it's over" and click to another episode lol
But if I had to choose it would be
Soul Eater ending 3 - Strength by Abingdon Boys School.

It was kinda hard choosing the opening themes cuz I have a good handful of great ones.

They are lots of animes which has a good opening. I like spice and wolf and gate"s opening and SAO's ending overfly was pretty good too.
